arteriovenous anastomosis – shorter vessel connecting an arteriole on to a venule and bypassing the capillary beds.
bicuspid valve – (also, mitral valve or remaining atrioventricular valve) valve Situated involving the still left atrium and ventricle; is made of two flaps of tissue.
capacitation – system that happens in the feminine reproductive tract through which sperm are ready for fertilisation; causes improved motility and alterations in their outer membrane that increase their capability to launch enzymes able to digesting an oocyte’s outer layers.
cleavage furrow – contractile ring that varieties about a cell throughout cytokinesis that pinches the cell into two halves.
articular tubercle – sleek ridge Found over the inferior cranium, promptly anterior into the mandibular fossa.
Bowman’s capsule – cup-shaped sack lined by a simple squamous epithelium (parietal floor) and specialised cells termed podocytes (visceral surface area) that take part in the filtration method; receives the filtrate which then passes on towards the PCTs.
The initial law of thermodynamics retains that Electricity can neither be created nor wrecked—it may only modify form. Your standard operate as an organism is always more info to consume (ingest) Vitality and molecules during the foods you eat, convert some of it into fuel for motion, maintain your body functions, and Develop and sustain your body constructions. There are two sorts of reactions that achieve this: anabolism and catabolism.
cytoskeleton – “skeleton” of a mobile; formed by rod-like proteins that support the cell’s form and supply, among other functions, locomotive abilities.
atrial natriuretic peptide (ANP) – peptide hormone made by the walls in the atria in reaction to higher blood pressure level, blood volume, or blood sodium that cuts down the reabsorption of sodium and drinking water during the kidneys and promotes vasodilation.
The third typical functionality with the skeleton is the fact that of movement. The nice the vast majority in the skeletal muscles are firmly anchored to the skeleton, typically to at the least two bones and sometimes to numerous bones.
anterior cardiac veins – vessels that parallel the little cardiac arteries and drain the anterior surface of the best ventricle; bypass the coronary sinus and drain immediately into the appropriate atrium.
aldosterone – hormone created and secreted from the adrenal cortex that stimulates sodium and fluid retention and will increase blood quantity and hypertension.
adrenal glands – endocrine glands located at the very best of each kidney that are essential for that regulation of the worry response, hypertension and blood quantity, h2o homeostasis, and electrolyte ranges.
basal mobile here – type of stem cell found in the stratum basale and while in the hair matrix that continuously undergoes mobile division, developing the keratinocytes of the epidermis.
